INDICATOR FOR INJECTOR PRESSURE KIERS.

Application filed November 12, 1921. Serial No. 514,839.

' to four thousand pounds, in order to attain the best results inpractice, I have found it to be essential that the height or top levelof the yarn or other material to be treated in the kier be maintained ata certain position with respect to or above the water level or height'ofthe liquor within the kier.

These kiers are of somewhat massive construction and after the yarn orother material has been placed therein for treatment and the kierclosed, (while it has been possible to ascertain the height of the waterlevel from a suitable water gauge) it has heretofore been impossible toascertain accurately the height of the top surface of the yarn, which isbeing treated with respect to the water level.

To obviate the foregoing disadvantages, I have devised a simple form ofindicating device which can be readily applied to existingkiers, wherebythe height or level. of the yarn or other material within the kier canbe readily ascertained, so that the height of thewater level or the topof the liquor within the kier can be correspondingly regulated in orderto give the best results, provision being also made for properly packingthe opening in the top of the kier through which the indicator passes,so that the interior of the kicr will be tight and there will be noescape ol the steam or pressure therein. 1

My invention in its broad aspect is capable of application to anystandard 01' conventional pressure kier and, in the present instance, Ihave shown it applied to what is usually termed an injector pressurekier, wherein the circulation of the liquid is eliected by means of asteam ejector, the

' steam passing down to the bottom of the kier and through an ejectordrawing the liquid through a pipe from beneath the false bottom of thekier and forcing it to the top thereof through an upright pipe whichconveys it through a nozzle back into the kier again, the water andliquid being supplied to the kier in proper proportions and any wastebeing withdrawn from. the kier according to requirements.

For the purpose of illustrating my invention, I have shown 1n theaccompanying drawings one form thereof which is at present preferred byme, since the same has been found in practice to give satisfactory andreliable results, although it is to be understood that the variousinstrumentalities of which my invention consists can be variouslyarranged and organized and that my invention is not limited to theprecise arrangement and organization of these instrumentalities asherein shown and described.

The figure represents a sectional view of my novel indicator device foran injector kier or the like, embodying my invention.

In carrying out my invention, which is applicable to any standardconstruction of pressure kier or injector kier 1, constructed ot thebody 2, bottom 3, top or dome 4:, and false bottom 5, provided with thesteam inlet pipe (3, injector 7, upwardly extending pipe 8, leading tothe head or nozzle 9, in which water and liquor are received. from thepipes 10 and 11 respectively, I provide the top 4: with a stuffing box12, through which passes the gauge rod or indicator 13, having thebottom plate or foot 14, which may be weighted if dcsircd, and rests onthe yarn or material to be treated and the knob or handle 15 at itsupper end. The rod or indicator 13 has thereon suitable grzuluations orindicating means, whereby the height of the yarn or other material 16contained in the kier can be readily determined, with respect to thewater level indicated by the line 17, the height of which at all timesbeing readily asccrt-ainml by the water gauge 18, which may be of any,conventional type. The kier is further provided with the bottom outlet19, leading to the pipe 20, communicating with the ejector 7 and havingthe valve 21 therein, from which the pipe 22 leads to the drain 23, saidvalve being operated by the handle 24 on the upper end of the valve rod25. said handle being readily accessible from the working floor 26.

The operation is as follows:

Liquor and water are introduced through the pipes 11 and 10 into thenozzle 9, and

commingled with the steam and liquid forced upwardly through, the pipe 8by the injector 7 and its adjuncts. The water level indcated by the line17, can be readily ascertainedby the water gauge 18 and the top of theyarn or other material can be ascertained by the graduations on theindicator or rod 13, and as it is desirable that the top of said yarn bemaintained at a certain predetermined point above the level 17, this canbe readily effected by regulating the supply of liquidto the kier or bywithdrawing the liquid through the-drains22 and 23. The stuiiing box 12effectively paclrs the opening in the top 4- and by my novel collocationof the indicator rod, with the water gauge, in a kier of the characterdescribed, I have produ ed a very e'liicient device for the purposeintended, and'one which is greatly superior to the lciers now commonlyin vogue. 7

It will now be apparent that l have devised a novel and useful indicatorfor injector pressure kiers, which embodies the features of advantageenumerated as desirable in the statement of the invention and the abovede scription, and while I have in the present instance shown anddescribed a preferred embodiment thereof which will give in practicesatisfactory and reliable results, it is to be I claim as new and desireto secure by Letters Patent, is

1. The combination with a pressure her having a gauge for indicating thelevel of liquid therein, of a vertically disposed slidable indicatingrod passing through the top of the kier to indicate above the top of thelatter the height of the material contained in the kier, the foot ofsaid rod resting on said material, whereby the height oi the materialmay be compared with the height of the liquid.

2. In an injector pressure kier having 'a. top provided with a stuffingbox, a vertically slidable indicator rod movable in said stutting boxand provided with graduations thereon, the footor" said rod beingadapted to-contact with the top of the material being treated in thekier, and a liquid indicator gauge located at the upper portion of saidkier, whereby the height of the liquid and the height of the materialcan be compared.
